Seven medals are up for grabs Tuesday, the 11th day of competition in Sochi, where fog has given way to rain.

If the weather cooperates, freestyle halfpipe skiing will make its Olympic debut, women's giant slalom and men's snowboard cross get underway, while the men's biathlon 15k will finally get its start after two consecutive days of delays.

Summer Olympic stars Lolo Jones and Lauryn Williams also make their Winter Games debut in the two-man bobsled race at Sochi's Sanki Sliding Center.

Ski Style: Best Tricks, Air and More

12:30 a.m. ET: American Mikaela Shiffrin makes her Sochi (and Olympic) debut Wednesday on the Rosa Khutor giant slalom course. The 18-year-old enters the competition a medal favorite as does Austrian Anna Fenninger, the Sochi super-G gold medal winner. USA's Julia Mancuso will also be on hand, though she is not expected to contend for a medal. Watch the first of two giant slalom runs here. The final begins at 4 a.m. ET here.

1:30 a.m. ET: Men's snowboard cross will finally get underway after thick fog forced organizers to cancel the event Monday. Look out for Americans Nate Holland, Nick Baumgartner, Trevor Jacob and Alex Deibold. Seth Wescott, who has won the gold every single time the event has been in the Olympics didn't make the team after returning from an injury. This leaves the field open to newcomers. Tune in here for the first elimination rounds. (A seeding round was skipped because of Monday's cancellation.)

2 a.m. ET: NBC has a second round of replays of Monday's men's aerials competition, figure skating and two-man bobsled.

Team USA: Medal Moments

3 a.m. ET: Both U.S. hockey teams have off Tuesday, but six other games are on the lineup, including four men's playoff qualification games, all available via livestream. First up is Slovenia-Austria. The winner will play Sweden in the quarterfinals. Watch here. Scroll down for details on three other games at 7:30 a.m. ET and noon.

5: 30 a.m. Maybe Tuesday will be the day the men's biathlon 15k mass start finally gets underway. The event has been cancelled two days ina row over a thick blanket of fog that moved into the Sochi area and has stubbornly hung around. If it does begin, Ole Einar Bjoerndalen could finally do what he has been waiting to do--win his 13th career medal and become the most decorated individual Winter Olympian. Watch him try here.

5:45 a.m. ET: Short track skaters compete for the medal podium in the women's 3000m relay heats. The event is not a U.S. strong suit, but tune in here for the penultimate day of action on the short track ice. The event wraps up Friday.

7 a.m.: Nordic Combined, the ski jumping-cross-country hybrid, continues Tuesday with the large hill, 10k portion. America's defending Olympic champion in the event, Bill Demong, is not expected to continue his reign. He placed 24th in the normal hill event last week. The favorites Tuesday are Akito Watabe from Japan and Magnus Krog from Norway. Tune in here.

7:30 a.m. ET: Russia plays the next hockey game of the day against Norway, which it has to (and should easily) beat to move on to its next matchup against Finland. Watch live here.

8 a.m. ET: Americans Emery Lehman and Patrick Meek go up against a crew of Dutch speed skating giants who could sweep Tuesday's 10,000m event. The Netherlands' best hopes are Sven Kramer (who notched the fastest time in the Vancouver race but was disqualified for failing to change lanes on a lap), Jorrit Bergsma and Bob de Jong. Tune in here.

10:15 a.m. ET: Lolo Jones and Lauryn Williams are back. The track stars make their Olympic bobsled debut in the two-man competition. Williams will be paired up with Elana Meyers. If she manages to win gold, she would be just the second athlete to do so in both Summer and Winter Games. Jones will be teamed up with Jazmine Fenlator and is going for her first Olympic medal, Summer or Winter. Watch the first two of four runs here.

12 p.m. ET: For even more men's hockey, check out the Czech Republic-Slovakia game here, and Switzerland-Latvia here. The winner of the former game will play the U.S. in quarterfinals, while the winner of the Switzerland-Latvia Game will advance to play Canada.

12:30 p.m. ET: Halfpipe is back, though this time the freestyle skiers will take a crack at the course. American David Wise is a gold-medal favorite. Teammates Aaron Blunck, Lyman Currier adn Torin Yater-Wallace will also compete in the debut Olympic competition. Watch live here.

3 p.m. ET: Tune in to NBC for some afternoon replays of the men's speed skating competition and individual large hill Nordic combined.
